RHYOLITE
Rhyolite can be considered as the extrusive equivalent to the plutonic granite rock, and consequently, outcrops of rhyolite may bear a resemblance to granite. Due to their high content of silica and low iron and magnesium contents, rhyolite melts are highly polymerized and form highly viscous lavas. They also occur as breccias or in volcanic plugs and dikes. Rhyolites that cool too quickly to grow crystals form a natural glass or vitrophyre, also called obsidian. Slower cooling forms microscopic crystals in the lava and results in textures such as flow foliations, spherulitic, nodular, and lithophysal structures. Some rhyolite is highly vesicular pumice. Many eruptions of rhyolite are highly explosive and the deposits may consist of fallout tephra/tuff or of ignimbrites.

Waarom overbieden gebruikers zichzelf?
Wanneer er wordt geboden, is dit het maximale bedrag dat een gebruiker bereid is te bieden op het product. Ons systeem zal dan automatisch namens die gebruiker bieden, waarbij het bod stapsgewijs wordt verhoogd om hun positie als hoogste bieder te behouden, tot aan het opgegeven maximum.
Als er een pictogram is dat 'Automatisch bieden' aangeeft, betekent dit dat ons systeem actief biedingen plaatst voor de gebruiker op basis van hun maximumbod. Dit kan lijken alsof gebruikers zichzelf overbieden, maar het is gewoon het gevolg van het feit dat het systeem het bod bijwerkt om de maximumlimiet van de gebruiker weer te geven.
